The figure labelled JKLM is a kite and the length ML is equal to 11.
What is a kiteA kite is a quadrilateral that have two pairs of equal length of sides and these sides are adjacent to each other. It can be viewed as a pair of congruent triangles with a common base.
The line JM bisects the kite into two congruent triangles, and thus;
the lengths ML and MK are equal.
ML = 5x - 4 and MK = 2x + 5 so;
5x - 4 = 2x + 5 {collect like terms}
5x - 2x = 5 + 4
3x = 9
x = 9/3 {divide through by 3}
x = 3
we substitute 3 for x;
ML = 5(3) - 4
ML = 15 - 4
ML = 11
Therefore, the value of length ML for the kite is equal to 11.

In triangle RG shown below. m 63 and m 30 Which of the following is the
63
Answer:
The value of the hypotenuse is 69.77 meters.
Step-by-step explanation:
To determine, in triangle RG, the value of its hypotenuse if its sides measure 63 meters and 30 meters, the following calculation must be performed, applying the Pythagorean theorem:
63 ^ 2 + 30 ^ 2 = X ^ 2
3969 + 900 = X ^ 2
√ 4869 = X
69.77 = X
Therefore, the value of the hypotenuse is 69.77 meters.
Solve for the value of v.
Answer:
9
Step-by-step explanation:
Since it is a straight line, therefore it will always be 180°
So...
(8v +3) +105 = 180
8v + 3 + 105 = 180
8v = 180 - 108
V = 72/8
= 9
Answer:
\(\boxed {\boxed {\sf v=9}}\)
Step-by-step explanation:
In the diagram, there are 2 angles: 105° and (8v+3)°. They are on a straight line together, so they are supplementary angles. They must add to 180 degrees. We can set up an equation.
\(105 + (8v+3) = 180\)
We are solving for v, so we must isolate the variable. First, we can rearrange the right side and combine the like terms (the constants without a variable).
\(105 +8v+3= 180 \\8v + (105+3) = 180 \\8v + 108= 180\)
108 is being added to 8v. The inverse operation of addition is subtraction. Subtract 108 from both sides of the equation.
\(8v+108-108= 180-108 \\8v= 180-108 \\8v=72\)
v is being multiplied by 8. The inverse operation of multiplication is division. Divide both sides by 8.
\(\frac {8v}{8}= \frac{72}{8}\\\)
\(v= \frac{72}{8}\)
\(v=9\)
v is equal to 9.

[~S & (R V S)] ≡ (Q ⊃ S) is true when A = T, S = F, R = F, and Q = T by substituting the propositional variables.
What is truth table?A truth table is a table used to determine the truth values of a compound proposition, which is a logical statement made up of simpler propositions using logical operators such as "and" (represented by "&"), "or" (represented by "V"), "not" (represented by "~"), conditional (represented by "⊃"), and biconditional (represented by "≡").
According to question:Let's substitute the given truth values for the propositional variables in the given statement:
[~F & (F V F)] ≡ (T ⊃ F)
Using the truth table for conjunction (represented by "&") and disjunction (represented by "V"), we can simplify the left-hand side of the equivalence:
[T & F] ≡ (T ⊃ F)
Using the truth table for conditional (represented by "⊃"), we can simplify the right-hand side of the equivalence:
F ≡ F
Since both sides of the equivalence have the same truth value, the statement is true.
Therefore, [~S & (R V S)] ≡ (Q ⊃ S) is true when A = T, S = F, R = F, and Q = T.

B. xy(y - x) (y + x)
Step-by-step explanation:
Given the points P (3, 5) and Q (-5, 7) on the cartesian plane such that R (x, y) is
the midpoint of PQ, find the equation of the line that passes through R and
perpendicular
to PQ.
Answer:
-22=22
Step-by-step explanation:
3,5-5,7=
-22/22
The equation of the line passing through R and PQ is 4(y - 6) = -x - 1/2.
To find the equation of the line passing through the midpoint R and the points P and Q, we first need to find the coordinates of the midpoint R. The midpoint coordinates can be found by taking the average of the x-coordinates and the average of the y-coordinates of P and Q.
The x-coordinate of the midpoint R is (3 + (-5)) / 2 = -1/2.
The y-coordinate of the midpoint R is (5 + 7) / 2 = 6.
So, the coordinates of the midpoint R are (-1/2, 6).
Next, we can use the two-point form of the equation of a line, which states that the equation of the line passing through points (x₁, y₁) and (x₂, y₂) is given by:
(y - y₁) = (y₂ - y₁) / (x₂ - x₁) \(\times\) (x - x₁)
Substituting the coordinates of R (-1/2, 6) and P (3, 5) into the equation, we have:
(y - 6) = (7 - 5) / (-5 - 3) \(\times\)(x - (-1/2))
Simplifying the equation:
(y - 6) = (2 / -8) \(\times\)(x + 1/2)
(y - 6) = -1/4 \(\times\)(x + 1/2)
4(y - 6) = -x - 1/2
Therefore, the equation of the line passing through R and PQ is 4(y - 6) = -x - 1/2.

Find the exact length of the curve. x = et − t, y = 4et/2, 0 ≤ t ≤ 6
Length of the curve is e² - 1 .
In arithmetic, a function from a group X to a group Y assigns to every part of X precisely one part of Y. The set X is termed the domain of the function and therefore the set Y is termed the codomain of the function
Main body:
A parametric curve is a function expressed in components form, such that;
x = f(t) , y = g(t).
The length of a parametric curve on the interval a ≤ t ≤ b is given by the definite integral :
L = \(\int\limits^a_b {\sqrt{\frac{dx}{dt}^2 + {\frac{dy}{dt}^2 } } } \, dx\)
Let's begin by getting the first derivative of the components of the function with respect to the variable t.
x = e^t - t
dx / dt = e^t−1
And, y = 4 e^t/2
dy /dt = 2 e^t/2
Substitute the derivatives into the following definite integral which computes the length of the parametric curve on the interval
[a,b]=[0,2].
L = \(\int\limits^a_b {\sqrt{\frac{dx}{dt}^2 + {\frac{dy}{dt}^2 } } } \, dx\)
L= \(\int\limits^2_0 {\sqrt{\ (e^t - 1)^2 + ({\(2e^{t/2}) ^2 } } } \, dx\)
L = \(\int\limits^2_0 {e^t - 1} \, dx\)
Evaluate the solution at the limits of integration to get the length.
L = (e² - 1 )- (e⁰ - 1)
L = e² - 1 - 1 + 1
L= e² - 1
Hence , length of the curve is e² - 1 .

For this case we observe that the time varies linearly with the obtained qualification.
The equation of the line can be obtained as follows
g-go = m (t-to)
where (go, to) are points that belong to the line.
To form the equation you need two points. These points are
(g1, t1) = (0,0)
(g2, t2) = (6.5.84)
Then, substituting, the equation of the line is
m = (84-0) / (6.5-0) = 84 / 6.5 = 12.923
g-0 = (12,923) * (t-0)
Rewriting.
g = 12.923t
